Abstract：This paper introduces an new “spherical model” formula of gravity’s middle layer correction algorithm, which considers the influence of earth curvature. We then, through different calculation examples, analyze error comparisons between the two algorithms. Results show that the magnitude of the maximum errors can reach 0.4 mGal, so this paper suggests that it is necessary to use the new gravity’s middle layer correction algorithm in surface gravity prospecting work.
